How to get the oil out of the oilsump when there is no plug?

[Peppe]

Hi !
I have seen some pictures of SP6 engines with a oil plug just behind the scavenge pump outlet. My 1999 SP6 engine doesn´t have this oil plug.
When I change the oil in the engine by just draining the drysump, the oil gets dark very quick after the change so there must be some dirty oil left in the sump on the engine.

Does anyone know how to get the oil out from the oil sump when there is no oil plug ?

What about taking the oil temp sensor out

[dxg]

in smart cars it gets sucked out the dipstick hole.

None of the above is possible.

There is no oiltemp sensor on a Cerbera SP6 and there aren´t a dipstick on the engine, the dipstick is in the dry sump.

Is the pick up pipe on the engine removable?
Or are the dry sump pupms mounted directly to the block?

If you can remove any engine pipes you will get a more oil out

The oil pressure relief valve under the hex plug, below the HP oil pump suction hose will only drain out part of the dry sump tank and not the engine sump



Also make sure you clean out the mesh filter on the scavenge return hose to dry sump tank



I guess you should machine a plug/drain in the sump if the engine is dismantled at anytime

The mesh filter is at the sump tank end of the scavenge hose, its under the flanged connection on mine.

Mine was full of hose rubber!

And what happens with the sealant for the engine when you put it together. On my car there was a lot of it on the edge underneath the camcover when I took it off. Some of that sealant may come loose and go around in the oilsystem and endup blocking some oilfeeds in worst case.

In the case of my Autocraft engine rebuild, silicone was in the finger followers and choking the oil scavenge return filter (same filter as depicted above), what a mess to clear out, had to flush the entire engine external oil flow system. My recent STR8-SIX rebuild, not wanting to take risks I checked both locations after approx 1500 miles and both are completely free of silicone crap.... sign (I would guess) of a more maticulous, careful rebuild procedure. Just over 2000 miles and supercharged engine sounds superb, running real well on an Emerald ECU thanks to a good rebuild and the mapping capabilities of TurboPACS in Co Durham, hardly a high mileage test I know, but further than I got with the Autocraft effort and with far more confidence.

Silicone was the reason for my rebuild, or as Dom called it foreign bodys!

Lucky me, the new camcover is sealed with a rubber gasket.
Have somebody made a gasket for the original camcover ?
If not, I think it would be a good idea since that is the part of the engine that should be taken apart to check the tappets, even if the engine is working fine. To check the tappets to often might do more damage than nessesery if you think about it like this.
